ABSTRACT

BACKGROUND:

Inflammation is known to play a crucial role in many diseases, including COVID-19.

OBJECTIVE:

Using flow-mediated dilatation (FMD), we aimed to assess the effects of inflammation on endothelial function in COVID-19 patients.

METHODS:

This study was conducted with a total of 161 subjects, of whom 80 were diagnosed with COVID-19 within the last six months (comprising 48 women and 32 men with a mean age of 32.10 ± 5.87 years) and 81 were healthy controls (comprising 45 women and 36 men with a mean age of 30.51 ± 7.33 years). We analyzed the findings of transthoracic echocardiography and FMD in all subjects. All results were considered statistically significant at the level of p < 0.05.

RESULTS:

The echocardiography and FMD of the COVID-19 group were performed 35 days (range 25-178) after diagnosis. There was no statistically significant difference in echocardiographic parameters. Differently, FMD (%) was significantly higher in the control group (9.52 ± 5.98 vs. 12.01 ± 6.18, p=0.01). In multivariate analysis with the forward stepwise model, FMD was significantly different in the control group compared to the COVID-19 group (1.086 (1.026 - 1.149), p=0.04). A Spearman's correlation test indicated that FMD (r=0.27, p=0.006) had a weak positive correlation with the presence of COVID-19.

CONCLUSION:

Our findings point to COVID-19-induced endothelial dysfunction, as assessed by FMD, in the early recovery phase.
RESUMO
FUNDAMENTO Sabe-se que a inflamação desempenha um papel crucial em muitas doenças, incluindo a COVID-19.

OBJETIVO:

Utilizando a dilatação fluxo-mediada (DFM), objetivou-se avaliar os efeitos da inflamação na função endotelial de pacientes com COVID-19.

MÉTODOS:

Este estudo foi realizado com um total de 161 indivíduos, dos quais 80 foram diagnosticados com COVID-19 nos últimos seis meses (48 mulheres e 32 homens com idade média de 32,10±5,87 anos) e 81 eram controles saudáveis (45 mulheres e 36 homens com idade média de 30,51±7,33 anos). Os achados do ecocardiograma transtorácico e da DFM foram analisados em todos os indivíduos. Resultados com p<0,05 foram considerados estatisticamente significantes.

RESULTADOS:

O ecocardiograma e a DFM do grupo COVID-19 foram realizados 35 dias (intervalo 25­178) após o diagnóstico. Não houve diferença estatisticamente significativa nos parâmetros ecocardiográficos. Em contraste, a DFM (%) foi significativamente maior no grupo controle (9,52±5,98 versus 12,01±6,18; p=0,01). Na análise multivariada com o modelo stepwise progressivo, a DFM foi significativamente diferente no grupo controle em relação ao grupo COVID-19 (1,086 (1,026­1,149), p=0,04). O teste de correlação de Spearman indicou que a DFM (r=0,27; p=0,006) apresentou correlação positiva fraca com a presença de COVID-19.

CONCLUSÃO:

Os achados deste estudo apontam para disfunção endotelial induzida por COVID-19, avaliada por DFM, na fase inicial de recuperação.
